JL5 Black Path Edition

Power Supply

    • Power transformer is encased in a separate nickel plated steel
      housing to contain the magnetic field.
    • Isolation transformer eliminates entry of AC power line noise
      into the amp, yielding greater benefits than add-on conditioners
      without any of their sonic drawbacks or expense.
    • Slow filament power-up extends tube life greatly.
      Quadruple cascaded audio power supply uses time
      compensated zero feedback mosfets and vacuum tubes to
      deliver unequaled dynamic contrast, resolution and sound
      stage realism

Circuitry

    • Pure Triode audio circuitry produces tonally natural music
      by eliminating the partition noise inherent in pentode designs
      and the resulting noise intermodulation (”grain”).
    • Low feedback (about 7dB) properly compensated design
      eliminates the tonal hardness of high feedback and/or
      improperly compensated designs while yielding more consistent
      sound quality.
    • Ultra-wide open loop in-circuit bandwidth of the output
      transformer enables operation of the amp’s closed loop
      response entirely within the open loop response, eliminating
      any requirement to use high feedback to force the output
      stage to perform beyond its natural capability.
    • Massive 15lb. output transformers allow the magnetics to
      operate at maximum linearity while still maintaining extremely
      low bass capability.
    • Unprecedented stability into capacitive loads. Fantastic for
      driving even the most difficult electrostatic speakers.
    • Black Path Edition Features
    • Amorphous Alloy core has less than 1/12 the hysteresis
      of conventional grain oriented silicon steel used by the
      competition, yielding a level of transparency no other tube
      manufacturer can match.
    • Low loss aerospace circuit board material.
    • Legendary Black Gate power supply capacitors.
    • Revolutionary BLACK PATH audio capacitors.

Chassis

    • Beautiful Golden Ratio proportions.
    • Mirror polished stainless steel maintains luster and brilliance
      with minimal care.
    • Heavy steel chassis for tremendous strength and the
      elimination of low frequency vibration, yielding incredible
      bass solidity and rock solid imaging.
    • Constrained damping layer on top plate silences vibration
      before it can be converted to electromechanical noise.
    • Output transformers are enclosed within their own
      magnetically isolated housing which is lined with Birch
      plywood – one of the most musical woods.
    • Mechanical isolation from floor vibration provided by
      anti-resonance viscoelastic feet.

Convenience

    • No user bias adjustments. Just plug in CAT supplied tubes
      and play.
    • OptiBias(TM) compensates for power line fluctuations up
      to 10% either way. Tubes always sound their best!
    • Tube life indicator. Green indicates the tubes are still good.
    • Red indicates time to replace.
    • Tubes operated at only 1/4 rated power for very long life
      expectancy.
